After the Spring Boot 2.5.0 update, it generates the myprogram-0.0.1-plain.jar file alongside the usual myprogram-0.0.1.jar. Can I disallow gradle to generate the *.plain.jar file? I use Gradle 7.0.2.
What I get:
build/
libs/
myprogram-0.0.1.jar
myprogram-0.0.1-plain.jar
What I want:
build/
libs/
myprogram-0.0.1.jar
build.gradle:
plugins {
id 'org.springframework.boot' version '2.5.0'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'
id 'java'
}
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
test {
useJUnitPlatform()
}
It was a change in Spring Boot 2.5.0.
As @ThomasKläger pointed out: You can set it in the build.gradle configuration.
build.gradle
jar {
enabled = false
}
For Kotlin devs:
tasks.getByName<Jar>("jar") {
enabled = false
}
Alternatively, you can run the bootJar task. It produces only the default runnable jar.
try use follow setting:
jar {
enabled = true
archiveClassifier = '' //use empty string
}
because org.springframework.boot.gradle.plugin.JavaPluginAction.java
private void classifyJarTask(Project project) {
project.getTasks().named(JavaPlugin.JAR_TASK_NAME, Jar.class)
.configure((task) -> task.getArchiveClassifier().convention("plain"));
}
from spring-boot-gradle-plugin sources file: https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-gradle-plugin/2.5.0/spring-boot-gradle-plugin-2.5.0-sources.jar
Instead of using the build gradle task you could use bootJar. That will only build the bootable jar.
Keep in mind that bootJar won't run your tests before building.
This gradle config will produce myprogram-0.0.1.jar instead of myprogram-0.0.1-plain.jar
In your build.gradle.kts
// Build executable jar
tasks.jar {
enabled = true
// Remove `plain` postfix from jar file name
archiveClassifier.set("")
}
